One of the first questions customers ask us is how much acoustic underlay costs. In our experience, buyers are often surprised by the range — from budget options under £5/m² to premium systems over £30/m². Here is the honest breakdown.
Price Ranges by Product Type
| Product | Approx. Cost Per m² | Performance |
|---|---|---|
| 3mm rubber (54dB) | Budget tier | 54dB ΔLw |
| 6mm rubber (74dB) | Mid-range | 74dB ΔLw |
| Cork-rubber composite | Mid-range | Good acoustic + thermal |
| SilentMat 15mm | Premium | Heavy use applications |
| 12mm acoustic system | Premium | 30dB + 58dB full system |
Is Cheap Acoustic Underlay Worth It?
In our experience, very cheap acoustic underlays (under £3/m²) typically have minimal real acoustic performance. The cheapest genuine acoustic product in our range is our 3mm rubber — it delivers real, measured 54dB improvement. Spending slightly more gets you significantly better results.
Total Project Cost
For a typical 20m² bedroom: 3mm rubber = very affordable. 6mm rubber = modest investment. The improvement in quality of life is disproportionate to the cost.
